VAR stands for Video Assistant Referee, and it is a technology-based system used in sports, particularly in soccer/football, rugby, and other sports, to assist match officials in making decisions during a game.
VAR works by having a team of video assistant referees who review decisions made by the on-field referee using video footage and communication technology. If the video assistant referees spot a clear error in a decision related to goals, penalty kicks, straight red card incidents, and mistaken identity, they can recommend that the on-field referee reviews the footage on a screen at the side of the field or inform them directly of the correct decision.
The primary aim of VAR is to reduce errors in crucial decisions and ensure fair play. Its implementation has been a topic of debate among fans and officials, but it aims to improve the overall accuracy of officiating in sports.
